Proton-Responsive Pyridine-Based Ligands. Synthesis, Coordination Chemistry and Catalysis

VIII-B Coordination Chemistry of Sterically Hindered Ligands and Multidentate Ligands, and Activation of Small Molecules

Thiolate complexes continue to attract considerable attention due to their unique chemical properties and structural diversity. Since thiolate groups meet the electronic and steric requirements necessary to stabilize a wide variety of metal complexes, they have been used as auxiliary ligands. On the other hand, thiolate complexes are known to undergo chemistry at the sulfur center, including ox...

Synthesis and Coordination Chemistry of Ligands for Supramolecular Chemistry and Sensing Applications

A series of multidentate N-donor ligands have been synthesised all containing pyridyl and pyridyl/thiazole units and their coordination behaviour is described. The ligands are classified into four types; i) terpyridine containing pyridyl/thiazole ligands (L); ii) pyridyl/thiazole ligands containing a 3,3′-disubstituted bipyridine core. (L); iii) 2,2′-bipyridine containing a crown ether moiety (...

Synthesis and coordination chemistry of tridentate (PNN) amine enamido phosphine ligands with ruthenium.

Tridentate amine-imine-phosphine ligands, R2PC5H7NC2H4NEt2 [(R)PNN(H)], where R = Pr(i) or Bu(t) are synthesized using a straightforward protocol of condensation, deprotonation, and addition of a chlorodialkylphosphine. Multinuclear NMR spectroscopy shows the ligands exist exclusively in the enamine tautomeric form in solution. Treating these ligands with RuHCl(PPr(i)3)2(CO) forms the desired c...
